Things change. Broken and restored, reused and remade, objects transcend their original functions, locations, and appearances. Locating material objects at the heart of the artistic, economic, and demographic transformations of the eighteenth century, this interdisciplinary volume expands beyond Eurocentric perspectives to discover the mobile, transcultural nature of eighteenth-century art worlds. Across ten diverse essays, each with a distinct scholarly approach, the volume charts new directions for art history and cultural history. Ranging from California to China, Bengal to Britain, the chapters illuminate transformations within and between artistic media, follow natural and human-made things as they migrate across territories, and reveal how objects catalyzed change in the transoceanic worlds of the early modern period. From porcelain to betel leaves, Chumash hats to natural history cabinets, this path-breaking volume examines how objects embody imperialism, knowledge, and resistance in various ways.
